Ultramarine Shadow

Ultramarine

Ultramarine is a deep blue pigment historically derived from lazurite, the principal component of the metamorphic rock lapis lazuli. The pigment was produced by grinding the stone and undergoing a complex washing process to isolate the blue mineral, which made it exceptionally valuable.

Shadow

A shadow is a dark area on a surface where light from a light source is blocked by an object. In contrast, shade occupies the three-dimensional volume behind an object with light in front of it. The cross-section of a shadow is a two-dimensional silhouette, or a reverse projection of the object blocking the light.
